A Collection Of Misfits, Kayla Gates

Master's Theses

The following creative writing thesis, A Collection of Misfits, includes a critically informed introduction which places my works of fiction within the larger conversation of contemporary fiction. These short stories explore numerous ways in which characters fail to connect to the world around them. Characters falter with relationships, religion, and fitting in. The collection also explores how the use of humor works to bridge the fissure that can form around a character who fails to connect–creating a personal connection between reader and character. Taken in sum, these stories indicate that we, as humans, have a binding thread that intertwines …

An Interdisciplinary Approach: Schizophrenia Derails Heteronormative Expectations In Psychological Narratives 2021, Bobbie Jo Weaver

Master's Theses

Required introductory psychology courses teach students a general and oversimplified version of the immense number of subfields within Psychology studies, much like introductory literature classes compress different genera throughout history into a miniscule number of “representative” texts. Nevertheless, these footholds generate an entryway into a whole new world of (specialized) exploration. Reading a text such as The Quiet Room: A Journey out of the Torment of Madness by Lori Schiller and Amanda Bennett provides a window for many students to crawl into one of Psychology’s darkest shadows, the field of abnormal psychology. Schiller’s non-fictional memoir, The Quiet Room, tells readers …

Found Media: Interactivity And Community In Online Horror Media 2021, Jax Mello

Master's Theses

Being isolated is a common fear. The fear can take many forms, from the fear of being the last one alive in a horrific situation to being completely deserted by everyone you love. This is a fear that has been showcased many different times in movies, novels, and every other piece of media imaginable. Although not always tied to the horror genre, the fear of being isolated is tightly intertwined with many horror stories. Therefore, it is interesting when a horror production goes out of their way to encourage interactivity within its audience. This goes beyond an artist’s desire for …

The Role Of Med12, Notch1, And Notch3 In Adipose Stem Cell Self-Renewal And The Integrated Use Of Stem Cells In Public Educational Materials, Rebecca Hodnett

Master's Theses

Human adipose-derived mesenchymal stem cells offer significant therapeutic potential as an ethically sound, easily accessed source of adult stem cells. To harness their medically relevant properties, it is necessary to understand the mechanisms that control their fate. Cell state and differentiation of stem cells is determined by interactions of signaling pathways, chromatin modifiers, and transcription factors working to regulate cell-type specific gene expression profiles. Specifically, both the MED12 subunit of the Mediator complex and the Notch signaling pathway are known to individually influence hASC self-renewal. We investigated the relationship between Notch signaling and transcriptional cofactor, MED12, to elucidate a potential …

Comparing Radiation Shielding Potential Of Liquid Propellants To Water For Application In Space, John Czaplewski

Master's Theses

The radiation environment in space is a threat that engineers and astronauts need to mitigate as exploration into the solar system expands. Passive shielding involves placing as much material between critical components and the radiation environment as possible. However, with mass and size budgets, it is important to select efficient materials to provide shielding. Currently, NASA and other space agencies plan on using water as a shield against radiation since it is already necessary for human missions. Water has been tested thoroughly and has been proven to be effective. Liquid propellants are needed for every mission and also share similar …

Node Classification On Relational Graphs Using Deep-Rgcns, Nagasai Chandra

Master's Theses

Knowledge Graphs are fascinating concepts in machine learning as they can hold usefully structured information in the form of entities and their relations. Despite the valuable applications of such graphs, most knowledge bases remain incomplete. This missing information harms downstream applications such as information retrieval and opens a window for research in statistical relational learning tasks such as node classification and link prediction. This work proposes a deep learning framework based on existing relational convolutional (R-GCN) layers to learn on highly multi-relational data characteristic of realistic knowledge graphs for node property classification tasks. We propose a deep and improved variant, …

Factors Leading To Structure Loss On The Thomas Fire, Rodolfo Uribe

Master's Theses

The recent surge in fire activity and the extent of displaced communities as a result of wildfire has increased awareness of wildfire issues nationwide (Syphard et al., 2017). Climate change, population growth, and continued development in the wildland urban interface (WUI) has contributed to a growing body of research into the underlying causes of this continued destruction (Kramer et al., 2019). There is no doubt that statewide policies, such as defensible space or building regulations, are associated with home survival (Keeley & Syphard, 2019). However, the relative effectiveness of wildfire mitigation depends on a myriad of factors specific to individual …

Clustering Web Users By Mouse Movement To Detect Bots And Botnet Attacks, Justin L. Morgan

Master's Theses

The need for website administrators to efficiently and accurately detect the presence of web bots has shown to be a challenging problem. As the sophistication of modern web bots increases, specifically their ability to more closely mimic the behavior of humans, web bot detection schemes are more quickly becoming obsolete by failing to maintain effectiveness. Though machine learning-based detection schemes have been a successful approach to recent implementations, web bots are able to apply similar machine learning tactics to mimic human users, thus bypassing such detection schemes. This work seeks to address the issue of machine learning based bots bypassing …

Adaptive Laboratory Evolution Of Scenedesmus Obliquus For Increased Carbohydrate Content And Biomass Productivity, Nahel Ali

Master's Theses

The economics of microalgal bioproduct commercialization would benefit from increased accumulation of energy storage compounds, such as carbohydrates and lipids, and increased biomass productivity. This thesis explores two adaptive laboratory evolution strategies for improving Scenedesmus obliquus: single UV-mutagenesis and low light cultivation at a high dilution rate to produce cultigens with greater carbohydrate content and iterative UV-mutagenesis and selection under outdoor conditions in a raceway pond at a high dilution rate to increase biomass productivity.

Two cultigens were generated with the goal of increased carbohydrate content: K5 and K7. Both were mutagenized for 5 seconds and cultivated in 50-mL …

The Effect Of Focused Ultrasound On Altering The Diameter Class Of Nerve Fibers Contributing To A Compound Evoked Potential, Analyzed Using A Perturbative Decomposition Technique., Megan Wurden

Master's Theses

Peripheral neuropathies are disorders that involve the damage of peripheral nerve fibers, affecting the ability of different parts of the body to communicate. A differentiating factor in diagnosis between various clinical conditions can be which size class of nerve fibers are affected. A nerve conduction velocity test can be used to assess the viability of the nerve but is a single-parameter test and gives no information about the population characteristics of the remaining active fibers. A method developed and previously reported by Szlavik (2016) utilizes a mathematical perturbed decomposition to determine the normalized frequency of each size class of fiber …

Towards A Complete Formal Semantics Of Rust, Alexa White

Master's Theses

Rust is a relatively new programming language with a unique memory model designed to provide the ease of use of a high-level language as well as the power and control of a low-level language while preserving memory safety. In order to prove the safety and correctness of Rust and to provide analysis tools for its use cases, it is necessary to construct a formal semantics of the language. Existing efforts to construct such a semantic model are limited in their scope and none to date have successfully captured the complete functionality of the language. This thesis focuses on the K-Rust …

Experimental Investigation Of The Effects Of Acoustic Waves On Natural Convection Heat Transfer From A Horizontal Cylinder In Air, Katherina V. Prodanov

Master's Theses

Heat transfer is a critical part of engineering design, from the cooling of rocket engines to the thermal management of the increasingly dense packaging of electronic circuits. Even for the most fundamental modes of heat transfer, a topic of research is devoted to finding novel ways to improve it. In recent decades, investigators experimented with the idea of exposing systems to acoustic waves with the hope of enhancing thermal transfer at the surface of a body. Ultrasound has been applied with some success to systems undergoing nucleate boiling and in single-phase forced and free convection heat transfer in water. However, …

Effect Of Simulated Storage And Distribution On Listeria Innocua Growth In Non-Traditional Salad Ingredients, Emma L. Sandquist

Master's Theses

The fresh-cut produce industry has seen expansive growth in recent years, to meet consumer demand ready-to-eat (RTE) salads have included the use of non-traditional ingredients. Uncommon ingredients include beet greens, kale, broccoli stalk, and Brussels sprouts, since these ingredients have not historically been consumed raw, potential food safety issues should be reassessed. Current processing technologies include produce washes that can reduce microbial levels but do not eradicate all populations. The lack of a kill step in produce processing emphasizes the need to minimize pathogen contamination during production and growth during a product’s shelf life. Listeria monocytogenes, a leading cause …

Estimating Food Waste Due To Food Safety Recalls And Investigating Ways To Minimize Negative Impacts, Mykayla Latronica

Master's Theses

For years the issue of food waste has been recognized and quantified; however, food safety issues often go unrecognized as a source of food waste. One objective of this research is to estimate quantities and monetary value of fruits and vegetables implicated in food safety recalls, and thus wasted. Using publicly available data we identified all recalls involving vegetable or fruit commodities contaminated with Listeria monocytogenes, pathogenic E. coli, or Salmonella during 2015-2018. When quantities were provided, monetary value of recalled product was calculated using USDA ERS 2016 average retail prices. Although data limitations only allowed analysis of …

Of The Wide-Eyed In Uncertain Times: The Education Of Girls During The Third Reich, Ingmar D. Clausing

Master's Theses

The aim of this thesis is to describe how both the state school system and the Hitler Youth educated girls during the Third Reich. Conventional theories have suggested a number of ideological suppositions regarding the overall curricular emphasis, but this study contends that such simplistic determinations do not capture the full spread of the educational experience. This thesis asks if girls in Nazi Germany were truly just indoctrinated or if schooling had legitimate academic purposes. Based on actual textbooks that were studied by girls for every subject area, at different grade levels, and in different types of schools, as well …

The Removal Of Sin In Second Temple Jewish Literature, Odiaka Walker

Master's Theses

Problem

This thesis explored the Second Temple literary background of the concept that Jesus appeared at the end of the ages to take away sin, in Heb 9:26. As such, the research question which guided the paper was: what did Old Testament and Intertestamental writers believe about the removal of sin at the end of the ages? The answer to this question infers other questions: who would remove sin? From where would sin be removed? How was sin defined? How would sin be removed? When would sin be removed (are there time specifications involved)?

Method

The terms ἀφαιρέω, ἀφίημι, ἀπαλείφω, …

Heteronormativity In Healthcare: Neoliberalism, Bio-Politics, And Necropolitics, Grace Avila

Master's Theses

This thesis will discuss heteronormativity in healthcare. It will take a social science and theoretical approach to acknowledge LGBTQ+ health disparities, apply theoretical approaches to why these disparities exist, and offer solutions to combat health disparities experienced by sexual and gender minorities. Neoliberalism, bio-politics, and necropolitics will be the theoretical approaches utilized to understand the basis of disparities experienced by the LGBTQ+ community. Neoliberalism will include themes of capitalism and public health policies which influence discrimination in healthcare. Bio-politics will outline how the intersection of the biological body and politics can exacerbate health disparities through the power of controlling bodies. …

Anti-Unionism And The Chicago Teachers Union, Paul Stromberg

Master's Theses

The Chicago Teachers Union (CTU) is one of the most influential political organizations in Illinois. Like other political organizations, the CTU influences policy through activism, advocacy, and endorsements. Unlike most political organizations, however, the CTU's 20,000 members are responsible for carrying out policy decisions through their roles as teachers, paraprofessionals, and clinicians in Chicago Public Schools (CPS). In response to this influence, anti-unionists have become increasingly adept at criticizing the CTU, using anti-union rhetoric to malign unionized teachers. Simultaneously, anti-unionists have utilized anti-union litigation to disable teacher unions, stripping them of guaranteed protections. Assisted by conflict theory, this study examines …

Plasmodium Tlap-2 Is A Microtubule-Associated Protein With Microtubule Stabilization Properties, Grifin Berge

Master's Theses

Microtubules facilitate major cellular and morphological changes in eukaryotic cells, including the protozoan parasite Plasmodium. Microtubule-associated proteins (MAPs), only very few of which have been characterized in the malaria parasite, regulate the highly dynamic microtubules. Thioredoxin-like associated protein 2 (TLAP2) is a MAP unique to the phylum apicomplexa, which in addition to Plasmodium includes the important human pathogen Toxoplasma. Here we report on the cloning and microtubule-binding activity of TLAP2 of the rodent malaria parasite Plasmodium berghei (PbTLAP2). PbTLAP2 is coded by a single exon gene and consists of 598 amino acids. The protein contains a putative C-terminal microtubule-binding domain. …

The Utilization And Optimization Of Omics Trait Prediction Models Within And Across Diverse Populations, Ashley Mulford

Master's Theses

Most cancer chemotherapeutic agents are ineffective in a subset of patients; thus, it is important to consider the role of genetic variation in drug response. Lymphoblastoid cell lines (LCLs) derived from 1000 Genomes Project populations of diverse ancestries are a useful model for determining how genetic factors impact variation in cytotoxicity. In our study, LCLs from three 1000 Genomes Project populations of diverse ancestries were previously treated with increasing concentrations of eight chemotherapeutic drugs and cell growth inhibition was measured at each dose with half-maximal inhibitory concentration (IC50) or area under the dose-response curve (AUC) as our phenotype for each …

Pseudomonas Aeruginosa Prophages And Engineered Temperate Phages, Genevieve Johnson

Master's Theses

The rising rate of antibiotic-resistant bacteria is a global health concern, and the Pseudomonas aeruginosa is estimated to be a leader in serious threats. Bacteriophages, or viruses that infect bacteria, have gained renewed interest in Western Medicine as an alternative to antibiotics. Phage therapy of P. aeruginosa infections has primarily focused on obligately lytic phages. However, prophages, or phages in the lysogenic life cycle, are estimated to far outnumber obligately lytic phages. In theory, these prophages can be genetically modified to be obligately lytic and thus ideal candidates for phage therapy. To date there has not been a comprehensive analysis …

Ethnic Racial Socialization, Ethnic Identity, And Internalizing Outcomes In The Context Of Stress Among Mexican Origin Families, Sarah Alicia Jolie

Master's Theses

Research demonstrates that it is important to study the impact of cultural factors on child development and well-being (Garcia Coll et al., 1996). Among Latino youth, ethnic racial socialization and ethnic identity have been associated with positive outcomes, such as academic competence and lower reports of internalizing problems (Liu & Lau, 2013; Berkel et al., 2010; Umaña-Taylor & Guimond, 2010). Additionally, there is evidence of ethnic identity mediating the association between ethnic racial socialization and child internalizing symptoms among Mexican-origin adolescents (Umaña-Taylor et al., 2014). However, more research is needed in examining these associations within stressful contexts relevant to Latino …

Rethinking Intimacy: Liberation Through Decolonial & Queer World-Making, Michelle Mae Mcguire

Master's Theses

Relationships play an important role in both the private and public spheres of our lives. If we understand our bodies to be the vessels through which we interact with all other objects, we come to understand the process of world-making as a summation of our relationships. Intimacy is the prevailing structure that helps assign meaning to these relationships. Intimacy binds together unfixed spatial and social relations that stretch across time and space. This essay examines the three intersecting sets of relations involved in intimacy as a means to deconstruct heteropatriarchal order and highlight the multiplicity of attachments and relationships that …
